When cold and warm air meet, the cold air is powerful, and it actively moves to warm air as a cold front, while warm air actively acts as a warm front. No matter what type of frontal precipitation is concentrated on the cold air side, the intensity, range and duration of cold and warm frontal precipitation are different, so the weather before and after crossing the border is different. Cold front is related to strong cooling, strong wind, rain and snow, while warm front often produces continuous precipitation. No matter what type of front crosses the border, it will be sunny before and after, and there will be precipitation when crossing the border (it is not necessary to have a front, but warm air is not good). Therefore, before the cold front crossed the border, it was sunny, with high temperature and low air pressure; When crossing the border, the weather is cool, windy, rainy and snowy; After crossing the border, the weather turned fine, the temperature dropped and the pressure increased. It was sunny before the warm front crossed the border, with low temperature and high pressure; When crossing the border, it is rainy; After crossing the border, the weather turned fine, the temperature rose, and the air pressure rose and fell.

Looking at my senior three children, I am also very anxious. I hope my answer can help you.
